Definitions

  • the present invention relates to a sanitary appliance for the collection and elimination of organic refuse. It relates in particular to an appliance comprising a WC and means for generating a flushing flow therein.
  • WCs are usually made of ceramic.
  • a bowl for collecting organic refuse is present therein, together with a sanitary trap connected to the bowl via an outlet.
  • the trap is often made of the same material as the bowl.
  • the bowl also comprises a ring for distributing flushing liquid over the bowl walls.
  • the distribution ring is also made of the same ceramic as the bowl and is formed integral with the bowl. This ring is fed with pressurized water during refuse discharge. The water feeding the ring either arrives directly from the water main via a valve which is operated when required
  • An object of the present invention is therefore to provide a sanitary appliance for the collection and elimination of organic refuse which always provides optimal cleaning of the bowl, eliminating any need for manual intervention.
  • Figure 1 is a section through an appliance formed in accordance with the present invention
  • Figure 2 is a very schematic view showing a detail of the appliance of Figure 1
  • Figure 3 is a simplified perspective view of the appliance of Figure 1 ;
  • FIGS 4, 5 and 6 are schematic diagrams of alternative embodiments of the appliance of Figure 1.
  • a sanitary appliance for the collection and elimination of organic refuse indicated overall by 1. It comprises a ceramic bowl 2.
  • a sanitary trap 3 is integrated into the appliance (and in particular into the bowl) and is connected directly to an outlet 4 provided in the base of the bowl 2.
  • the appliance also comprises a cistern 6, connected by pipes to a distribution ring for a flushing liquid (generally water) contained in the cistern 6.
  • the cistern 6 comprises known means for its filling to a predetermined level; these are not shown.
  • the cistern content is indicatively three litres, this being the fluid quantity necessary to effect correct bowl flushing.
  • a dip tube is inserted into the cistern 6 and directly connected to the intake of a pump 10.
  • the pump presents a delivery connected to the distribution ring 7 via a first shutoff valve 8.
  • the pump delivery is also connected to a conduit 11 feeding a nozzle 12 inserted into the sanitary trap 3; the conduit is intercepted by a second valve.
  • the nozzle opens into the first concave part of the trap, directly downstream of the bowl outlet 4.
  • the nozzle is orientated such as to aid the exit flow through the trap by creating a sucking effect on the organic materials present in the bowl.
  • the distribution ring is made of synthetic material and is applied to the bowl at its top (rim), in a suitably arranged recess.
  • the ring presents a plurality of delivery nozzles, each of which generates a flushing jet. These jets have a particular orientation to the bowl walls.

  • the control circuit operates the pump 10 and, when the fluid is under pressure, opens the first valve 8 to generate a bowl cleaning flow.
  • the control circuit then also opens the valve 9 and the nozzle 12 creates a jet which puts the bowl interior under negative pressure, facilitating the expulsion of the organic refuse present in the bowl, via the trap.
  • the combination of the flow generated by the optimally directed nozzles, its pressure and the sucking effect, provides excellent cleaning of the bowl surface from the organic refuse.
  • the WC of the present invention is fitted with two pushbuttons. A first enables a light cycle with a water quantity from 1 litre to 1.5 litres to be set, while the second sets a normal cycle with a water quantity from 2 to 3 litres. It should be noted that the presence of the pump enables the appliance to also be used in a configuration in which the cistern 6 is below the level of the distribution ring 7.
  • Figure 4 shows a device of the present invention represented very schematically. It shows for simplicity the bowl/ring/cistern/trap unit indicated by 30, the pump 10, and a collector 31 connected to the trap.
